Duplicate Tail Like Right Lower Limb: A Rare Congenital Malformation
Journal of pediatrics & neonatology, 2020
Introduction: Polymelia (supernumerary limbs) or congenital duplication of limb is an extremely rare condition in humans, with only few cases reported in the literature. Case Report: This is a case of newborn female born with a tail-like extra right leg, which unfortunately was not detected during the routine antenatal ultrasonography. Conclusion: Early diagnosis can facilitate the management planning and psychological preparation of the parents. Surgical resection of the accessory limb at an early age is recommended in patients with polymelia.
Tail-like congenital duplication of lower extremity (extra leg or vestigial parasitic twin)
Ethiopian Journal of Health Sciences, 2018
BACKGROUND: Congenital duplication of lower extremity, either complete or incomplete is extremely rare. Only 26 cases had been reported till 2010, of which only 5 cases had feature of complete duplication. Theories have been proposed that the cause of this abnormality includes maternal factors like diabetes and usage of teratogenic drugs. Duplication of lower extremity may mimic that of vestigial parasitic twin; phenotypically, it appears as an individual with extra appendage or limbs. Vestigial parasitic twis are very rare comprising only 10% of all conjoined twins). Conjoined twin by itself is rare because the survival rate after birth is approximately 25%. CASE DETAILS: A 5-year old female patient came from a rural area of Ethiopia was referred to our hospital for radiological diagnosis and to assess the vascular supply. No family history of similar congenital abnormality was identified. No known history of chronic illness or maternal usage of teratogenic drugs was identified either. CONCLUSION:A child with parasitic twin and complete duplication of lower limb is reported .Tail-like soft tissue was found arising from sacral area. CT scan findings confirmed the duplication of the lower limb bones. Fatty tissue was the major component of the soft tissue almost replacing the muscle.Reconstructed CT angiography images showed major arterial blood supply of the parasite limb. Surgical intervention was done successfully.This type of case is unusual. It is the rarest type of lower limb duplication KEYWORD: congenital duplication of lower limb, vestigial parasitic twin, pseudo tail
A rare case of unilateral postaxial duplicated foot in a developmentally normal child
Journal of orthopaedic surgery (Hong Kong), 2017
Diplopodia, being a rare congenital disorder, is infrequently discussed in published texts. Most reported cases have accounted the involvement of duplicated preaxial digits with other associated organ system and physical deformities. Here, we present an unusual case of isolated diplopodia involving postaxial toes in a child with no other organ and physical abnormalities. Radiological studies revealed a set of 10-digit-duplicated foot over the lateral aspect of the native foot, complete with phalanges and its corresponding metatarsals as well as tarsals, supplied by an anomalous posterior branch of the popliteal artery. Definitive surgery was performed just before the child was learning to walk.
Anatomy & Cell Biology
Polymelia is an extremely rare congenital anomaly where an individual is born with an abnormally developed extra or supernumerary limb which is generally shrunken and functionless. A case of thoracomelia (a type of polymelia) was observed macroscopically and confirmed radiologically in 1.5 years old boy born in Nepal with an abnormal supernumerary upper limb attached to his back in the thoracic region. The limb was successfully amputated, and the boy had a favorable outcome after surgical treatment, without any adverse effects or impairment. Understanding the embryogenesis of thoracomelia is essential for unraveling the complex mechanisms underlying this condition and potentially aiding in early diagnosis and intervention. This case report and review aims to shed light on the intricate processes governing forelimb formation and their perturbations leading to thoracomelia.
Femoral duplication: A case report
American Journal of Medical Genetics, 1989
Femoral duplication is a rare anomaly that has been described as an isolated entity and in association with other congenital defects. Since the description by Erlich in 1885, 24 additional cases have been reported. The present report concerns a 34-week black female infant with apparent bilateral femoral duplication associated with a meningocele and abdominal, genitourinary, vertebral, and lower-limb anomalies. The cause is unknown. Femoral duplication is a developmental field defect, hence causally heterogeneous.
Lower Extremity Rare Preaxial Polydactyly. A Case Report and Literature Review
SAR journal of surgery, 2023
The condition known as pediatric foot polydactyly can manifest itself in a broad range of malformations, from a single extra digit that is only connected to the rest of the foot by a thin band of connective tissue to intricate central foot duplications that involve the duplication of tarsal bones. The presentation of preaxial polydactyly of the foot is crucial to understand, even though it is quite uncommon. This is because in over half of the cases, several congenital malformations, such as syndactyly and atrial septum defects, have been described. The result of surgical reconstruction should be a foot that is stable, mobile, and pain-free, with five aesthetically pleasing toes. This should allow the patient to wear standard footwear and walk without experiencing any discomfort.
Congenital Limb Deficiency: A Case Report
Journal of Nepal Medical Association
The complete absence of limbs is a rare occurrence. Though the causes are various, it is hard to elicit most of the time. They are usually diagnosed via anomaly scan but the lack of access to the same can often lead to a term presentation. It is still not uncommon to receive pregnant patients at term to the hospital or in labour as the first antenatal visit. Increasing the feasibility of the scan can help in the early diagnosis and management. Here, we report a rare combination of limb defects that we managed in a district-level hospital and highlight the difficulties in the management and referral of the patients while working in rural areas.
Clinical profile of congenital limb anomalies in neonates
International Journal of Contemporary Pediatrics, 2018
Background: Reported birth prevalence of congenital limb defects vary from country to country. Epidemiological studies permit the timely detection of trends in congenital limb anomalies and the associations with other birth defects. The objective of this study was to know the prevalence and the variety of congenital limb anomalies and their association with other anomalies.Methods: A prospective observational study in which all newborns reported to the neonatal department were surveyed to find out the incidence, diversity and association of limb anomalies. Age of the mother, risk factors and other demographic data of the newborns was analyzed. Babies born less than 28 weeks were excluded from the study.Results: The prevalence was 6.34 per thousand live births. The majority of the neonates were term babies and female. 28 % of the babies were born out of consanguineous marriage. The mean age of the mother was 25. Median parity was 1. 9.52 % of the babies had a history of anomaly in th...
